JAMES K. DIAMOND, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO CLIPPER BELT LAGER COMPANY, OF GRAND RAPIDS, MICHIGAN.

BELT LACER.

Application filed January 31, 1923. Serial No. 616,187.

To all whom it may concern Be it known that I, JAMES K. DIAMOND, a citizen of the United States, residing at Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Belt Lacers, of which the followingis a specification.

This invention relates to improvements in belt lacers.

The main objects of this invention are:

First, to provide an improved belt lacing hook a plurality of which may be easily inserted or set into the belt, the engaging clamps being clinched in an effective manner to retain them and minimize the cutting and tearing of the belt and the distributing of the strain thereon.

Second, to provide an improved belt lacing which is very secure and durable.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a plan view of a belt lacing embodying the features of my invention, portions of the belt being broken away.

Fig. II is a detail longitudinal section on a line corresponding to line 22 of Fig. I.

Fig. III is a transverse section on a line corresponding to line 3-3 of Fig. I, the hooks being shown in full lines for convenience in illustration.

Fig. IV is a detail transverse section on a line corresponding to line 4-4 of Fig. I, portions being shown in fulllines for convenience in illustration.

Fig. V is a side view of one of the hooks in its closed position or the position it assumes when set into a belt.

Fig. VI is a side view of one of the hooks open.

Fig. VII is an end elevation of one of the hook arms.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little.

is a name current in the trade for this class of devices) is preferably formed with arms of unequal length as illustrated. These arms terminate in inwardly projecting prongs 4, preferably disposed at an acute angle to the arms,-see Figs. V and VI. The prongs are flattened on one side, as at 5, to taper the prongs and I provide clinching tips 6, there being in the structure illustrated a bevel 7 at the end of the flattened portion. However, this instead of being in two flat cuts as illustrated may be formed with a rounded cut with substantially the same result. It is, however, desired that. the plane of the surface 7 shall be at a greater angle than that of the surface Theflattened sides are preferably the adjacent sides as illustrated.

When these hooks are set into a belt, which is usually accomplished by machines adapted to set the seals and at the same time properly space them, the prongs are driven through the belt and their clinching tips clinched or turned over as shown in Figs. III and IV in direction transverse to the longitudinal plane of the hook. By forming the clinching points in this manner the direction of their clinching is predetermined, thatis, the hooks with the clinching points turn in the same direction, thus distributing the clamping action uniformly throughout the belt.

My improved belt lacing is very secure. The prongs do not spring or yield in the belt as it passes over-the pulley which yielding wears the belt and greatly shortens the life of the lacing. By overcoming this I provide a lacing which is of great strength and durability.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. As an article of manufacture, a belt lacing hook having arms of unequal length terminating in inwardly projecting prongs disposed at acute angles thereto, the adjacent sides of the prongs being flattened and terminating in bevel, the plane of which is at an angle to the plane of the flattened sides to taper the prongs and provide clinching points.

2. As an article of manufacture, a belt lacing hook having arms terminating in inwardly projecting prongs, the adjacent sides of the prongs being flattened and terminating in bevel, the plane of which is at an angle to the plane of the flattened sides to taper the prongs and provide clinching points.

3. As an article of manufacture, a lacing belt hook the arms of which terminate in inwardly disposed prongs flattened to provide a clinching point disposed at one side of the longitudinal plane of the prong and adapted to turn in a predetermined direction when the hook is set into a belt,

4. A belt lacing comprising a belt and a plurality of belt lacing hooks set therein side by side in spacedrelation, said hooks having arms of unequal length terminating in inwardly projecting prongs flattened on one side to a'clinching tip, the clinched tips lying transverse to the longitudinal planes of the hooks.

5. A belt lacing comprising a belt and a plurality of belt lacing hooks set therein side by side in spaced relation, said hooks having inwardly projecting prongs flattened on one side to a clinching tip, the clinched tips lying transverse to the longitudinal planes ofthe hooks.

In Witness whereof, I have hereunto set my hand and seal.
